Solution

Step 1:
$(2 w - 9) + (- 4 w - 5) = 2 w + (- 9) + (- 4 w) + (- 5) {r e w r i t e a s s u m} = 2 w + (- 4 w) + (- 9) + (- 5) {C o m m u t a t i v e p r o p e r t y} = [2 w + (- 4 w)] + [(- 9) + (- 5)] {G r o u p l i k e t e r m s} = (- 2 w) + (- 14) {C o m b i n e l i k e t e r m s}$
Final Answer: $- 2 w - 14$
